Zion Williamson’s stepfather solicited and accepted a $400,000 payment from a marketing agent in October 2018 prior to his only season at Duke Blue Devils, according to a court motion and sworn affidavit filed by his former marketing representative’s attorneys in federal court on Thursday. Gina Ford’s attorneys say the affidavit and other exhibits show that Williamson was ineligible when he played for the Blue Devils in 2018-19 because his stepfather received impermissible benefits from Slavko Duric, a Canadian marketing agent.
